Fibrous histiocytoma of the trachea.

Intratracheal tumors are rare in children. A case is reported of a two-year-old female child with a fibrous histiocytoma of the trachea which caused severe respiratory obstruction and persistent right middle lobe pneumonia. Fibrous histiocytomas are basically benign tumors of histiocytes and have been mistaken for other tumors such as fibroma, sclerosing hemangioma, neurilemoma, fibromatosis, hemangiopericytoma, fibrosarcoma, and some primitive sarcomas. Fibrous histiocytomas have not been reported in the trachea or bronchi. The patient was treated with endoscopic removal of the tumor, and has remained free of disease to this date.
